The media outlets argue Zimmerman's claims of self-defense are not a confession and therefore are not shielded from public records laws.

Original: New evidence in the Trayvon Martin murder trial could emerge in the next few weeks, but both sides are reportedly fighting the release of a voice stress test that defendant George Zimmerman took after the shooting.

The Florida State Attorney office announced the second round of discovery evidence could be released after Thursday.

But before media outlets get their hands on the new information, a Florida judge will decide if some evidence should be re-sealed.

Florida judge Kenneth Lester will decide Friday whether a voice stress test that indicates Zimmerman was telling the truth when he claimed he shot Martin in self-defense should be kept out of the public eye, Click Orlando reported last week.

Both the state and the defense want the voice stress test kept under wraps, citing the test isn't reliable and could prejudice the public.

Zimmerman's team of attorneys is also fighting to keep his emails and text messages sealed. His lawyers are asking Lester to block the release of about 1,000 emails Zimmerman sent to the city of Sanford about the case, Click Orlando reported.

Media lawyers are expected to attend Friday's hearing, arguing the public has a right to know the information.
